The manual ‘Understanding Groundwater & Wells in manual drilling’ complements the 4 technical training handbooks and highlights those essential subjects which are relevant to manual drilling, geo-hydrology, hygiene, well installation and well development in practice, in simple and
how to drill a well using the manual well drilling method only. Whereas typical hand drilling techniques require a hand to be placed over the spout of the drill stem to act as the valve, the Baptist method uses a valve incorporated into the drill bit at the bottom of the drill stem (or elsewhere in the stem). The
Machine-drilled wells are often very expensive and not affordable by large parts of the population in developing countries. Another option is to drill ‘shallow’ water wells (up to about 35 meter depth) by hand, so reducing the price of a well by a factor 4 -10 compared to a machine-drilled borehole.
These practical handbooks create awareness of manual drilling for affordable water supply and a roadmap for implementation of manual drilling programs. The manuals provide an extensive and detailed guide for trainers and drilling teams in the use of various drilling techniques for making affordable boreholes.
